The next major service point I have reached on my 120:
500 hr inspection £8,450
Several minor anti-corrosion treatments undertaken at the same time, the swashplate re-shimmed, and I swapped one of the radios. (additional cost to above)
Then igniter box failed - £4,806 to replace, done in 2 days.
She is running absolutely smoothly. The current known problems remain:
1. An over-wound clock! (perils of self-fly hire). Need to take out and release the spring, then re-install
2. Occasional fuse-pop on the strobe - will have this investigated for frayed wire then replace if needed
3. Blade tape used to denote the "blue" rotor has come off (replace)
